Render the selection specified by `selection` for `page` to the given cairo context. The selection will be rendered, using `glyph_color` for the glyphs and `background_color` for the selection background.

If non-NULL, `old_selection` specifies the selection that is already rendered to `cairo`, in which case this function will (some day) only render the changed part of the selection.

`page` : | the PopplerPage for which to render selection
`cairo` : | cairo context to render to
`selection` : | start and end point of selection as a rectangle
`old_selection` : | previous selection
`style` : | a PopplerSelectionStyle
`glyph_color` : | color to use for drawing glyphs
`background_color` : | color to use for the selection background

Render the selection specified by `selection` for `page` into `pixbuf`. The selection will be rendered at `scale`, using `glyph_color` for the glyphs and `background_color` for the selection background.

If non-NULL, `old_selection` specifies the selection that is already rendered in `pixbuf`, in which case this function will (some day) only render the changed part of the selection.

`page` : | the PopplerPage for which to render selection
`scale` : | scale specified as pixels per point
